To (1 7071/0721 it nmgl concern.-

Be it known that I, FREDERICK W. FLINT, of Chicago, Tillinois, have invented certain new and useful Improvements in Tobacco- Pipes, of which the following is a specification.

This invention relates to improvements in tobacco-pipes; and it has for its objects to provide a simplified and improved construc tion wherein the smoke is compelled to pass through a tortuous and extended passage on its way from the bowl of the pipe to the mouthpiece, said extended passage being formed of pipe-sections freely exposed to the atmosphere and good heatconductors, so as to rapidly cool the smoke, and to provide in a construction of this character simplified and improved details which enable all parts to be conveniently and thoroughly cleaned, while at the same time their construction is such that the pipe may be manufactured at a minimum cost.

To the above ends the invention consists in the matters hereinafter described, and more particularly pointed out in the appended claims, and will be readily understood from the followingdescription,reference being bad to the accompanying drawings, wherein- Figure 1 is a view in side elevation of a pipe embodying myinvention. Fig. 2 is a similar view of the stem portion of the pipe with parts shown in axial section to disclose the internal face view of that one of the unionpieces adjacent to the pipe-bowl with its detachable side removed. Fig. 3 is an inside view of the union-piece. Fig. 5 is an outer face view of the removable side of the unionpiece shown in Fig. 3, this side plate being of the same construction as that of the unionpiece of the mouthpiece end of the same. Fig. t is an inside face view, s'imilarto that of Fig. 3, of the union-piece with which the stem is connected.

Referring to said drawings, 1 designates the bowl of the pipe, which may be of any suitable or preferred construction; 2, the mouth piece, and 3, a, 5, 6, and 7 a series of pipe sections arranged to extend between unionpieces 8 and 9, which pipe sections and unionpieces constitute the stem of the pipe.

The nnion pieces 8 and 9 consist each of a main circular body portion, as 10 and 11, re-

spectively, having formed in its interior a plurality of chambers, the union-piece 8 having two main chambers 12 and l3,separated by a transverse partition 1 1, and the union-piece 9 having three chambers 15, 16, and 17, respectively,likewise separated from each other by partitions 18 and 19. \Vithin one side of the body of each union-piece is arranged to fit a dislolike plate, as 20 21, conveniently having screw-threaded engagement with the union-body and forming, in conjunction with the several partitions, chambers having no communication with each other except through the several pipe-stems, as will hereinafter appear. Each plate 20 21 is provided with a number of apertures corresponding to the number of stemsections, (in the present instance five,) four of these apertures being threaded for engagement with the ends of the four shorter pipesoctiOns, while the fifth aperture (in the present instance the central one) is made of sullicient size to permit the central stem-section to extend bodily therethrough.

in the preferred construction illustrated the four shorter pipe-sections are provided at their respective ends with right and left screw-threads, which engage the correspondingly-threaded apertures of the disks 2O 21., and in order to insure greater certainty of fit in the joints between said pipe-sections and said plates said apertures of the plates are countersunk slightly, as indicated clearly in the drawings, and the abutting shoulder portions of the pipe-sections correspondingly doubled to engage therewith. The central pipe-section 3, with which the bowl of the pipe is connected, is provided at one end with a suitable plug 22, adapted for engagement with the neck of the pipe, while its opposite end extends into the union piece 9 through the main chambered portion thereof and is threaded into the inlet end of a port or passage 23, which extends radially through that portion of the body in rear of the main chamber portion and opens into and communicates with the chamber 15, as best indicated in Fig. i. From the chamber 17 a second pas sage 2 L extends out through the body of the union-piece to a central outlet 25, with which the mouthpiece 2 is connected.

The parts constructed as described may he conveniently assembled by firstuniting the two disks or plates 20 21 with the ends of the four outer and shorter pipe-sections, the rightand-left arrangement of the screw-th reads of said pipe-sections enabling this to be accomplished without difficulty, after which said plates are threaded into their respective unionpieces. The central pipe-section 3 is next passed in through the central aperture of the union-piece 8 and threaded into the unionpiece 9, as hereinbefore'described, the pipebowl and mouthpiece being afterward connected with the stem in the usual manner.

The circulation of the smoke through the stem of the pipe when constructed and arranged as described will be as follows: Entering the central section 3, the smoke will pass through the latter to the connectingpassage 23 and thence to the chamber 15, passing from this chamber through the pipesection 4 to the lower part of the chamber 13, from the upper part of this chamber back through the pipe-section 5 to the upper chamber 16 of the union-piece 9, thence back to the union-piece 8 through the pipe-section 6, to the chamber 12, back by the pipe-section 7 to the chamber 17, and thence to the mouthpiece through the passage 2t.

In practice the same sections will be made of a good conductor of heat, preferably thin metal tubing, and when thus constructed the extended passage through which the smoke travels on its way from the bowl to the mouthpiece will insure that the smoke be thoroughly cooled. This effect is insured by reason of the fact that the several stem-sections are supported entirely free from each other and exposed throughout their entire surface area to the surrounding air.

A feature of great importance also is the construction of the stem of detachable pipesections, which are severally straight and to which access may be readily had for cleaning. It will be obvious that the smoker may cleanse the pipe readily by simply removing the central stem and thereafter disconnecting the group of four outer pipes together from the two union-pieces, after which any suitable instrument may be passed directly through the pipe-sections to cleanv the latter withoutdisconnecting them from the disks or end plates. Obviously when the end plates have been removed from the union-body the latter may be cleansed with the utmost expediency. A pipe constructed in accordance with my invention therefore possesses not only the important advantage of thoroughly and efie'ctively cooling the smoke, but also is capableof being thoroughly cleaned in the most convenient manner.

It will be obvious that the details of construction may be varied to some extent without departing from the spirit of the invention, and I do not therefore wish to be limited to the details shown except to the extent that they are made the subject of specific claims.

I claim as my invention 1. In a pipe of the character described, the combination with the bowl and mouthpiece, of a stem composed of a plurality of substantially straight pipe-sections arranged to extend alongside of each other and freely exposed at their exteriors to the atmosphere, the ends of said pipe-sections being arranged to communicate to form asingle extended tortuous passage for the smoke, as set forth.

2. In a pipe of the character described, the combination with a bowl and mouthpiece, of union-pieces located respectively at the bowl and mouthpiece ends of the stem, a plurality ofsubstantiallystraightpipe-sectionsextending between said union-pieces formed of good heat-conducting material and freely exposed at their exteriors to the atmosphere, and communicating ports in said union-pieces whereby the ends of said pipe-sections are placed in communication to form a single, continuous passage for the smoke.

3. In a pipe of the character described, the combination with a bowl and mouthpiece, of union-pieces respectively located at the bowl and mouthpiece ends of the pipe, each havin g a removable side plate, a plurality of pipesections interposed between said union-pieces and having their ends engaged with apertures formed in the respective side plates, one of said pipe-sections being connected with the duct of the pipe-neck and another with the duct of the mouthpiece, as and for the purpose set forth.
